To all whom z't may concern.'

Be it known that I, CLIFFORD G. Cizoon, a citizen of the United States,and a resident of Pittsburgh, in the county of Allegheny and State ofPennsylvania, have in vented a new and useful Improvement in Machinesfor Packing Goods; and I do hereby declare the following to be a full,clear, and exact description thereof.

Myl invention relates to a machine for packing goods, and' has specialreference to the packing of goods, such as candies in boxes, whereingoods of the same kind and shape, or goods of different kinds andshapesarle packed in boxes for 'shipment or for sa e.

Heretofore, in the packing of goods, such as candies, and particularlywhen it is desired to pack a large number of boxes at one time, theempty boxes are laid upon a table against each other, and then each ofthe packers hasy a large box or receptacle in his hands or in his armsor on his arms, with each containing different candies to be placed insuch empty boxes. In this case,

the packers are required to walk around such table while picking out thecandies from their boxes or receptacles, so that they can place therequired amount or number' in each of the empty boxes, and thus a greatdeal of time was consumed in this process due to the packersinterference with each other.

It was also very laborious for the packers on account of the walking andcarrying which was necessary.

The object of my invention is to overcome these objections anddiiculties by providing a cheap, simple and efficient machine forpacking these goods, which will do away with carrying of the goods to bepacked, will overcome the walking required, and will enable the goods tobe packed in a much faster time.

A still further object of the invention is to provide such a machine onwhich the trays for carrying the different goods or candies to be packedwill be capable of having dif'- ferent and intermittent speeds for thepurpose of packing boxes of different sizes or quantities.

To these ends my invention consists, generally stated, in the novelmachine for packing goods, as hereinafter more specifically set forthand described and particularly pointed out in the claims. p

To enable others skilled in the art to which my invention appertains toconstruct and use my improved machine for packing goods, I will describethe same more fully, referring to the accompanying drawings, in which:

Figure 1 is a side elevation of my improved machine for packing goods;

Fig. -2 is a sectional lan or top view of thesame, taken on the line 2 2Fig. l, looking in the direction of the arrows;

Fig. 3 is an end View of the machine, taken on the line 3-3 Fig. l,looking in the direction of the arrows; Fig. 4 is a cross-section of themachine, on the line 4-4 Fig. 1 looking in the direction of the arrows;

Fig. 5 is a sectional view showing one of the power driven sprocketwheels employed and its operating lever, and taken on the line 5 5 Fig.3;

Fig. 6 is a View showing a portion of the gearing mechanism;

Fig. 7 is a section of the gearing mechanism on the line 7-7 Fig. 3,looking in the direction of the arrows;

Fig. 8 is a View of the tray hanger;

Fig. 9 is an enlarged sectional View of the trays and carrying chain forsame; and

4 Fig. l0 is an elevation of one of the trays.

Like symbols of reference indicate like parts in each of the figures ofthe drawings. As illustrated in the drawings, my improved machine isshown at A, and is formed from and supported by suitable frame work 1built up from the floor a.

Within the frame 1 and on each side of the machine is a separate chain2, which passes over sprocket wheels 3, 4 at each end of the machine andmounted on the shafts 5 and 6. The shaft 5 is mounted in suitableadjustable bearings 5 at lthe front end of the machine A and the shaft 6is mounted in suitable bearings 6 at the rear end of the machine. chains2 are the receiving trays 7, whichare pivotally connected to said chainsthrough the hangers 8, such pivots being indicated at 9, and being atthe upper ends of such hangers in order that the trays will have aswinging or tilting motion, but will always remain in a horizontalposition for receiving and carrying the goods to be packed in themovement of the chains. The trays 7 will also be removable from'thehangers 8 Extending across between thev separa-ble and resting upon theremovable ange portions 8' placed on ledges 8 on said hangers, andupwardly extendlng anges 7" are also formed on said portions to hold thegoods to be packed on said trays, such portions and plates being held bysaid ledges resting on the same, with the portions resting in a seat 9in said ledges. l

Mounted upon the floor a is a suitablemotor 10 which has a small pulley11 mounted upon the main shaft 12 of the same and around which pulleyand a larger pulley 13 mounted on the cross-shaft 14 a belt 15 passes. Asmall sprocket wheel 16 is also mounted on the shaft 14 and around suchwheel and a larger sprocket wheel 16 on the cross shaft 17 a chain 18passes. A sprocket wheel 19 is also mounted on the shaft 17 and aroundwhich and a larger sprocket 4wheel 2O on the cross-shaft 21 a chain 21passes, which shaft 21 has suitable gearing mechanism, B connectedtherewith, as hereinafter described. l

Above the trays 7 and supported by the frame-work 1 is the storage binor receptacle 22 for the elnpty boxes to be lled, which is provided withinwardly tapered open sides 23, formed of strips of wire cloth, and anopening 24 below each of the same, so that such boxes will-be directedto such openings and against the bottom`22 of said bin to enable them tobe withdrawn through the openings when desired, as hereinafterldescribed.`

Extending along each side of the frame work 1 and exteriorly of themachine A is a bench 25, and under each of the same is a conveyer belt26, which passes over'a pulley 27 at the front end of the machine andover a pulley 28 in a wrapping table 29, at the rear end of the machine.A supporting shelf 30 extends out from the frame-work 1 under the upperportion of the belt'26 to hold the same level and permit it to slidealong the same, and a guard 30( extends out from such frame under thelower portion of such belt to keep the same from sagging down andinterfering with the operatives. y

Mounted on the shaft 6 is the sprocketwheel 31 around which passes asprocketchain 32, which also passes around a sprocket wheel 33 mountedon a shaft 34 carrying' the pulley 28, while an idler 35 mounted underthe table 29 engages withf the bottom portion of the belt 26 to hold thesame taut in passing over the pulleys 27 and,

28, and such belt through these connections is adapted to run at aslower rate of speed than the trays 7.

The gearing mechanism B is connected up with the shaft 21 and mountedupon one `side of the machine A, and upon said shaft 21 adjacent thesprocket wheel 20 is the sprocket wheel 36, and 'such wheels are of thesame diameter, A chain 37 passes Mounted upon the shaft 21 -on theopposite side of the ,machine A from the wheels 2O and 36 is a gearwheel 41, which meshes with a larger gear wheel 42 mounted'on a shaft`43 above and in line with. the shaft 21, and mounted on said shaft 43are the two gear wheels 44 and 45, which are of the 'same diameter,except that the wheel 44 is provided with only a toothed section 45thereon for engagement with the gear wheel 46 when desired. This wheel46 is movably mounted on a `shaft 47 whichis above and in line with theshaft 43 andsuch wheel is adapted to be moved along said shaft "47 bymeans of a yoked lever 48 engaging with a Y hub 49 on one sidey of thesame. A gear wheel 50 is also mounted upon the shaft 47 and meshes witha smaller gear wheel 50' mounted upon the shaft 6 which is also aboveand inline with said shaft 47.

The use and operation of my improved machine for packing goods is asfollows:

When the machlne A is placed in operation in any suitable'manner'by anysuitable means, such asY the motor 10, acting through the shafts 12, 14,17 21, 43, 47 and 6 will through the interposed connections betweenl thesame, as previously described, operate,

ico

so that the conveyer formed by `the chains 2 and trays 7, as well as thebelt 26 will travel in the direction of the arrows, shown in Fig. 2, Thetrays 7 being provided with the goods to be packed and the storage binl22 provided with the empty boxes desired, such boxes can be packed inthe following manner.

In the case -of mixed or assorted candies,

boxes or receptacles containing the same are placed upon the trays 7,with two ofthe same kind upon each tray, as described, and

the girls or other operatives are seated along each of the benches 25,so that as each operator pulls out an empty box from the bin 22 throughthe openings 24 and by holding the same in one hand or by placing thesame on the bench 25, they can with the other hand pick the amount ofcandy desired from the receptacles passing along in the trays 7 in frontof such operators. When the operatives have filled the boxes, they arethen placed on the belts 26 which carry the same back into the table 29where they are re` 'moved from the belts by the operatives seated aroundsuch table and the lids placed on thesame, after which they can beweighed l bythe operators around thetable 29, and

wrapped in the usual manner.

In case it is desired to change the speed of the moving trays 7, such asfor instance, when larger boxes are, to be packed, the clutch 39 is sooperated by the lever 40 to enga e with the sprocket wheel 20 and suchwliee being connected by chain 2l and with the sprocket wheel 19 on theshaft 17, as pre- -viousl described, the shaft 21 is operated at a sower speed than whenthelsprocket- Wheel was engaged by said clutch owingto the diiferences in sizes of the wheels 19 and 36. This slowermovement of the shaft 21 will operate the shaft 6 through the gearing Bat a slower speed and allows the operatives more time when packinglargerr boxes.

When it is desired to pass still larger boxes and where several piecesare to be taken from the same receptacle on the trays 7 or from the saidtrays, an intermittent` drive is provided by theshifting of the gear 46into engagement with the gear 44, at which time such gear 46 will beoperated intermittently by reason of the toothed portion or segment 45on said gear 44 and such trays will move forwardly along and then stopin front of the operatives for a predetermined period, so that theoperatives may have sufiicient time to extract as many pieces as desiredfrom such trays in the packmg of said larger boxes. e

It will thus be seen that by reason of the change inspeeds of shaft 2land the continuous and intermittent gearing between shafts 43 and 47 insuc-h gearing B, variations of speeds, either continuous orintermittent, may be obtained.

It will also be seen that my improved method and machine for packinggoods will enable the operatives to sit easily and comfortably aroundthe machine and pack the goods quickly and easily, and thus overcome thelaborious and irksome task of walking around a table carrying the goodsto be packed.

It will further be seen that the goods to be packed will be within easyreach of theoperatives at all times and the empty boxes for packin willalso be within reach, so that a continuous and steady packing of thegoods can be kept up and maintained during the operation of packing andwrapping the goods.

V It will also be obvious that the operatives.

will be enabled to work faster and steadier without interference witheach other in the packing of goods, and by reason of the arrangement ofthe device the operators are enabled to pack the goods fromA each of thetrays in passing and each of the packed goods will be carried away fromthe machine ior weighing and wrapping. This arrangement of the devicewill also permit the trays to travel through the machine continuouslyand iny a horizontal position at all times, and they will not be liableto spill, drop or emgtg'A the goods to be packed which are carrie ythem. l

It will be understood thaty my improved machine for packin goods may beused for the packing of goo other than candies or other like goods, andwhen used in connection with such goods, candies of different kind andshape and of the same shape and kind can be packed either by .beingindividually packed in the boxes from the trays or inbatches.'

Various modifications and changes in the design` and vconstruction of myimproved mac ine may be resorted to without departing from the spirit ofthe invention or sacrifcin an of its advantages.
